Tokyo, Japan, May 30, 2018 --- Kyowa Hakko Kirin Co., Ltd.

About Mogamulizumab
Mogamulizumab is an investigational humanized monoclonal antibody (mAb) directed against CC chemokine receptor 4 (CCR4), which is frequently expressed on leukemic cells of certain hematologic malignancies including CTCL (cutaneous T-cell lymphoma). Mogamulizumab was produced using Kyowa Hakko Kirin's proprietary POTELLIGENT® platform, which is associated with enhanced antibody-dependent cellular cytotoxicity (ADCC).
In August 2017, the FDA announced that mogamulizumab has been granted Breakthrough Therapy designation status for the treatment of MF and SS in adult patients who have received at least one prior systemic therapy. In late November 2017, the FDA accepted the BLA for filing and granted mogamulizumab Priority Review.

About Mycosis Fungoides (MF) and Sézary Syndrome (SS)
MF and SS are the two most common subtypes of CTCL, a rare type of non-Hodgkin's lymphoma, which is characterized by localization of malignant T lymphocytes to the skin, and depending on the stage, the disease may involve skin, blood, lymph nodes, and viscera.
